INSULATING CONNECTOR FOR WIRES Filed May 1,. 1941 INVENTOR Mike VaraATTO R N EY Patented Sept. 15, 1942 UNITED STATES' PATENT OFFICE 4Claims.

This invention relates to new and useful improvements in an insulatingconnector for wires.

More particularly, the invention purposes the construction of aconnector as mentioned, capable of tightly connecting wires together ina simple way.

More specifically, the invention proposes to characterize the connectorby a tubular housing having a closed end and adapted to receive group ofwires into its open end, and a simple novel arrangement for holding theinner ends of these wires connected together.

More specifically, the invention contemplates providing a metallic sheetturned around the end portions of the wires and acting in a certain wayin conjunction with portions on the tubular housing for forming thedesired connection,

Still further it is proposed to form one of the wires at its inner endwith a loop engageable with a complementary longitudinally extendinggroove formed on the inside of the tubular housing in a manner toprevent the wires from turning relative to the tubular housing.

Another object of the invention is the construction of a device asmentioned which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth,

In the accompanying drawing forming a material part of this disclosure:

Fig. 9 is a perspective view similar to Fig. 8, but illustrating a groupof wires made of three wires. 4

The insulating connector for wires, in accordance with this invention,includes a tubular housing I0 having a closed end II and an open end I2.The housing III is also provided with an internal longitudinallyextending groove I3 extended inwards from its open end I2. The housingIII also has an external head It) by which it may be convenientlygripped. A group of wires I4, I5 have one of their ends twisted togetherforming a coil I6. More specifically, the wire I4 forms the core of thecoil I6 while the wire I5 is wound around this core portion. The WiresI4 and I5 have insulating covering material M and I5 respectively, alongtheir length except at the twisted end portion. The wire I4 has its freeend formed into a loop portion I'I.

When the engaged ends of the wires I4 and I5 are inserted into thetubular housing the loop I! will have its top (see Fig. 2) disposed withthe groove I3 to prevent the wires from turning relative to the tubularhousing II).

A metallic sheet I8 is turned around the twisted ends, that is, the coilI6 of the wires I4 and I5. The metallic sheet I8 is formed from a pieceof sheet metal bent substantially into tubular shape. A clamping member20 is mounted on the housing II! and abuts against the metallic sheet I8for holding said sheet and the coil I6 of the wires I4 and I5 inposition. More specifically, this holding member 20 comprises a screw ofinsulation material mounted through one wall of the housing III.

With the parts as illustrated in Fig. 2 the wires I I and I5 areelectrically connected together and securely held within the casing IB.

If desired, the wires I4 and I5 may be removed by first loosening thescrew 20 and then pulling out on the wires. The metallic sheet I8 maythen be slightly opened to permit its being slipped off the coil I6.

In Figs. 6' and 7 a modification of the invention is illustrated whichis similar to that previously described except that a metallic sheet isnot engaged about the coil I6. In this form of the invention the wiresare inserted into the tubular housin I0 and the holding screw 20 isrotated inwards to cause its inner end to bear directly against the coilI6 to hold the wires in position within the tubular housing III.

In Fig. 8 a perspective view of the inner ends of the wires I4 and I5 isillustrated to show the manner in which the inner end of the wire I5 iswound around the inner end of the wire I4 to form the coil I6.

In Fig. 9 a perspective view of a group of wires formed of threeseparate wires is shown. In

this form of the invention wires [5 and I5 are wound around the innerend of a wire M to form a coil [6,

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

1. An insulating connector for wires having a tubular housing with aclosed end and a group of wires enclosed within a metallic sheathinserted into said housing through its open end, a clamping member onone side of said housing and engageable against said sheath for holdingsaid sheath and wires against outward movement relative to said housing,and means holding said wires against rotation relative to said housingfor assisting said clamping member in securely locking said sheath andwires within said ho ing.

2. An insulating connector for wires having a tubular housing with aclosed end and a group of wires enclosed within a metalic sheathinserted into said housing through its open end, a

clamping member on one side of said housing and engageable against saidsheath for holding said sheath and wires against outward movementrelative to said housing, and means holding said wires against rotationrelative to said housing for assisting said clamping member in securelylocking said sheath and wires within said housing, comprising a loopformed on the inner end of one of said wires and having its top portiondisposed within a longitudinal groove formed in said housing.

3. An insulating connector for wires having a tubular housing with aclosed end and a group of wires enclosed within a metallic sheathinserted into said housing through its open end, a clamping member onone side of said housing and engageble against said sheath for holdingsaid sheath and wires against outward movement relative to said housing,and means holding said wires against rotation relative to said housingfor assisting said clamping member in securely looking said sheath andwires within said housing, comprising a loop formed on the inner end ofone of said wires and having its top portion disposed within alongitudinal groove formed in said housing, said groove being extendedinwards from the open end of said housing enabling said loop to beproperly engaged within said groove from the time said wires areinserted into said housing.

4. An insulating connector for wires having a tubular housing with aclosed end and a group of wires enclosed within a metallic sheathinserted into said housing through its open end, aclamping member on oneside of said housing and engageable against said sheath for holding saidsheath and wires against outward movement relative to said housing, andmeans holding said wires against rotation relative to said housing forassisting said clamping member in securely locking said sheath and wireswithin said housing, comprising a loop formed on the inner end of one ofsaid wires and having its top portion disposed within a longitudinalgroove formed in said housing, said wire having said loop being extendedbeyond the inner end of said sheath and other wire.
